Extensible SSEL Beacon Parser for HAM Operators

Andrew Seel Summer 2013 REU Project August 2, 2013

SLIDE 2

FIREBIRD Science

Requirements

Monitor serial stream
Identify, collect, and validate SSEL packets
Send validated SSEL packets to SSEL
Select mission of interest (e.g. FIREBIRD, EPISIM)
Display and/or plot variables of user interest
Distributable as a single executable (Not Open Source)

Programming Language

Python 2.7
Tkinter

–

Cross-platform GUI toolkit

Matplotlib and Numpy

–

FIREBIRD Science

Current Progress

Barebones GUI
Serial Port selection

–

Attempts to autodetect ports on the system

–

Allows for user to type in port name if correct port isn't detected

Detects FIREBIRD packets

–

Unstuffs, Checks CRC, Checks spacecraft ID fields

Parses FIREBIRD packets into Python Dictionaries

–

{“BEACON_SYSTEM_TIME_YEAR”: 2013, “BEACON_SYSTEM_TIME_MONTH”: 8, etc}

Graphs user selected variable from a series of packets

–

Updates when a new packet is received or variable selection changes

To Do

Verify serial data parsing with data from the Firebird

engineering unit

List the remaining variables in the bottom right quadrant

–

Use values from either first packet or packet currently highlighted in the packetLog

Export packets to SSEL
Write GUI_CLASSes for other missions
General GUI cleanup
